The Ecosteno's configuration can be found here: https://github.com/aerickt/qmk/blob/357a7a942a65f604050a3aefab2e14f21d9cbbc4/keyboards/noll/ecosteno/config.h#L50-L51
The Multisteno's configuration is here: https://github.com/aerickt/qmk/blob/357a7a942a65f604050a3aefab2e14f21d9cbbc4/keyboards/noll/multisteno/config.h#L26-L27
By default double tap chord repeat is enabled, but 1-up is commented out; simply uncomment those lines to enable.
Note that the Ecosteno firmware has only been tested to work on the older version with blue switches. There is a slight change in firmware between the pink and the blue version. The configuration between the two is here: https://github.com/aerickt/qmk/blob/47e9e766f7f820d95a6b7faba3ce3e021eb0aa35/keyboards/noll/ecosteno/config.h#L31-L41
Although this firmware hasn't been tested on the Ecosteno with pink switches, it should, in theory, work.
If you are just a hobbyist using Plover, you should not be using TX Bolt; Gemini PR is simply the better option if you had the choice.
TX Bolt is not supported due to limitations of this older QMK fork. If you need TX Bolt (e.g. for use with Case CATalyst) I'd suggest flashing the precompiled firmware provided by nolltronics (Ecosteno link and Multisteno link). These unfortunately do not support any of the firmware mods such as 1-up or chord repeat.
This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line.
The docs are powered by Docsify and hosted on GitHub. They are also viewable offline; see Previewing the Documentation for more details.
You can request changes by making a fork and opening a pull request, or by clicking the "Edit this page" link at the bottom of any page.
The project also includes community support for lots of other keyboards.
QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu. The OLKB product firmwares are maintained by Jack Humbert, the Ergodox EZ by ZSA Technology Labs, the Clueboard by Zach White, and the Atreus by Phil Hagelberg.
